BACKGROUND OF THE INVENTION I. Field of the Invention The present invention is roughly related to data communication in a wireless communication network. 11 · The background is particularly related to the data rate transmitted between two points in the honeycomb r: 5. The rate of data transmission between the two points is higher than that between the two points. The industry knows that in this case, multiple links are used in parallel to ^ Ϊ (ppp) ° η # ^ ^ ^ ^ t ^ ^ Point-to-point accounted for qf tr) agreement, you can pass the power of ppp from ^ J will use Ye p Xi link agreement. This agreement was described by Sklower in the Request for Comments (RFC) No. 1 990 (August 1996) of the Internet Engineering Project (ρΕτρ) Network Working Group, and is described here for reference. Logical data links such as multiple integrated services digital network (I SDN) bearer channel splitting, reassembly, and method of sorting data.

Even though the heavy link protocol requires special multilink modems, the standard telephone modems currently installed on most computers are not compatible. In the honeycomb field, the IS-9 5 standard coded multidirectional proximity (CDMA) communication developed by the Telecommunications Industry Association (T IA) provides what is known as the medium data speed (MDR) and high data speed (HDR) for the South Speed Features of data service transmission. When the user data rate between the mobile station (MS) and the base station subsystem (BSS) exceeds the data channel rate of the ordinary CDMA, MDR and HDR allow multiple simultaneous

Heavy data channel. Since one direction often has a larger amount of data to transmit than the other direction (most commonly in the forward direction, that is, from to ...), the number of channels opened in both directions need not be equal. In MDR, it is used in all directions, typically there is a basic code data channel, which together with the data carries the signal and up to 7

The Lei Nianji group is not marked with PHONE 1, PHONF 9 η electrolysis, 7 _ 2, · · ·, PHONE η and indicates that any predetermined number of modules are clear. Lingbei can be used for this predator. The inventor found

582145 V. Description of the invention (7) The number of convenient telephone modules used by the nested unit 28 is between 2 and 6; 30 equal-numbered modules are used. For convenience and robustness, the transceiver uses a common antenna (not shown). Each phone module is in a cellular type _ = its own phone number, in order to facilitate the execution of the number, it is preferred that each phone module 36, 37, 38 of the cellular unit 28 transmits data to the unit 3 over a cellular network. _Module. J = The received data is demultiplexed by the corresponding multiplexer 34, according to which: the second multiplexer 32 is transmitted to the individual computer. ^ For clarity of multi-hygiene devices and numbers ", the individual and power blocks are used to explain. These two functions are preferably performed by the same processing unit, and most preferably by a general-purpose processor with appropriate input / output nodes and software. In addition, the modem simulator 32 and the multiplexer 34 can be executed on Yuan hardware or a combination of software and hardware components. Figure 2 is a flowchart illustrating a preferred communication unit 28 according to the present invention. And 30 is between 22 and 24 of the computer's transmission data. For clarity, the method described below refers to 4 ^ :: transmitted by the computer, but it must be understood that the computer communication usually through units 28 and 3. The computer communication is for dialing instructions. Step 50. The user of the brain 22 uses standard Microsoft dial-up connection. From the arrival & +,? To the Mingyi prompt, enter d, the formula: dial-up request. Typical user by The soft electric home is just the code. In response to this, the user sets the phone number of the first phone module 36 in the bee 30 (pH ONE, factory J code: planned by the pre-program. When the user's input 2 is received ^; When the electric rule of WJ is broken, t brain 22 sends a dialing instruction to unit ⑼. 王

V. Description of the invention (8) ^ In response to the dial-up instruction, the caller 90 is called the initialization step 52, and the caller module 36, 37, 38 is set up to the caller to establish an n-way call. When the corresponding module of Bayou Zaofan 30 called. As shown at the same time, when the return of Step 54 is successfully established, the call is successfully established, the unit 28 is ready to connect to the finger link :: to the computer 22 'send a notification to the computer, and the data unit 28 is as if the unit is; Count; Dagger: The computer can start sending data to Dan when using only a single Hive: D modem-like. However, the data transmission rate is roughly the same as the receiving data frame; it can reach Π times the rate. Receive PPP information frame. In the computer simulator 32, the computer 22 sequentially displays its dedicated-to-frame pointers in the sequence. Then the multiplexer 34 adds the frames 36, 37, and 38 to the frame: Better multitasking? Assign each frame to the phone module. However, the f phone module == sends the data frame to the corresponding part of the whole unit in a bad way. … Passing step 62 will pass the data frame to the slip. It will be sent during the link between units 28 and 30… link lost. This loss of connection is often caused by unit 1 but may also be due to unit 28 or 3. Hardware failure of Gongyi 34 regularity test phone module%, 37 cases. If it is confirmed that it is still connected to the other unit, it is still valid. When the link is no longer valid, multiplexing: = Sending, with-Degree becomes a data frame for transmission. When the honeycomb link is operated again, the data transmission speed between the computers 22 and 24 is still maintained. Once the module is rebuilding its honeycomb chain: Then V. Description of the invention ( 9) Know the multiplexer, and then resume sending data. "When the data communication is over, the computer 2 and the module will give it back. Computer 2 2 ends the connection with computer 2 4. The user 2 instructed the car body # to hang up at step 6 4 to end the connection. The same dial-up unit 28 of the computer initialized the connection instructs the telephone modules 36, 37, and sends a request to cancel the connection to the unit 28, 30 also notifies the computer 24 that the connection has ended 38 and hangs up its individual call. Unit FIG. 3 is a flowchart schematically showing a preferred embodiment of the present invention for receiving a transmission between units 28 and 30. The method of data transmission described above with reference to FIG. This method is performed with and continues until the end of the link. Can be completed in parallel between units 28 and 30 at the same time between units 28 and 30. #Receive the bell instruction 'in the modem simulation step 6; = number: "" 26 received the information to the modem of unit 30 to cry 32. = data stack initialization message. At this time, the computer 24 is ready to receive data from the computer 22. In: In the material receiving step 70, the multiplexer 34 receives the data frame from the telephone module ⑼, =, 38. The multiplexer system The forks are received in the order in which the data frames arrive at the module, but the order is often different from the order in which the computer 22 sends out the data frames. For this reason, in the reordering step 72, the multiplexer buffers the data frames, and The unique numbering information added to the data frame is reordered. At step 74, the numbering layer is removed from the data frame. At the sending frame step 76, the modem module 32 is sequentially connected through the cable between the modem simulator and the appropriate computer port. The data frame is presented to the computer 24. " Figure 4 is a flowchart illustrating the details of the reordering step 72, thereby

The data frames received by $ 工 & 34 are sorted for output in the proper order. This step is triggered whenever a new frame is received, or in addition, when Γ has not received a frame when the timer has expired. Typically, the timer is based on "the network's message response characteristics are set to expire after 7 seconds. The number of parameters" is used in the flow chart to indicate that a special period is added at step 5 8 (Figure 2). To each box number. "Second Count" is a parameter used to indicate the number of the next data frame sent / received in advance. Received the out-of-order second; if the box's comparison is determined with the current next-count value, then: I, the buffer is collected until its number sequence is reached. Value: When I data unit 34 receives a data frame, its count value is larger than the current next count. If the values are different, the comparison value is different from the predetermined window, and the amine is different. The window size is typically set to 8 frames, and the window size indicates the extent to which the data frame ‘ϋίϋ remains within the collection. If the difference between the count value and the time of this exchange is greater than 0 but within the window size, the current frame is increased to 24.框 All the frames in the collection are sent to the computer in the order of their counts. The second episode: The record and the slot that can hold the received data frame are marked as Delivery: To Correspondence = # 料 架 has been sent out. Then times—count value reaches;. Take the value of the last box count value greater than 1, the multiplexer waits for the second-frame other face, the right multiplexer 34 receives a box whose count value matches the next one, and the effect is given to the computer 24, and the corresponding registration mark is collected. Suspend for 1 $ state, and check the rest of the registration in the collection, and '办 定 Αθ 隹 j㊉ will be sent.
